To all whmn it may concern:

Be it known that I, GEORGE H. FIsHER, a citizen of the United States,residing at Plainfield, in the county of Union, State of New Jersey,have invented certain new and useful Im rovements in Blind-Fasteners;and I do dec are the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to an improvement in blind-fasteners, and has forits object to provide a device for preventing sparrows and other birdsfrom roosting on the keeper of the fastener behind the blinds anddisfiguring the side of the building.

It also has for its object to provide a device which is exceedinglysimple, inexpensive, and durable in construction and easy and effectivein use.

It consists of the several features and combination of features, as morefully hereinafter described and claimed.

Referring to the drawings, Figure 1 is a side elevation of theblind-fastener with my invention in place on the keeper thereof andshowing a portion of a blind and a buildingwall. Fig. 2 is a front viewof the keeper. Fig. 3 is a side view of a modified form of disk orwheel. Fig. 4 is another modified form of the device, showing the diskor wheel mounted just above and independently of the keeper.

In the drawings, in which like numerals of reference denote like partsthroughout the several views, 1 represents the side wall of thebuilding; 2, the keeper of the fastener, which is screwed into the wall1 and is designed to engage with the hook'8 upon the blind 4.

5 indicates the space between the wall and the blind in which thesparrows are accustomed to occupy while roosting on the keeper. Thekeeper is provided with an upwardly extending spur 6, provided with avertical slot 7, and 8 is a circular disk or wheel made, preferably, ofthin steel or other suitable material. In the modified form of disk orwheel shown in Fig. 3, 9 indicates the disk, which is provided with aseries of points 10.

In the modification shown in Fig. 4 the disk or wheel 11 is mounted on ashaft 12, secured to the side of the house independent of and just abovesaid keeper. By mounting the disk on a separate shaft, as justdescribed, it can be used with any and all blind-fasteners, no matterwhat their style may be.

I do not desire to be understood as limiting myself to the specificdetails of construction and arrangement as herein described andillustrated, as it is manifest that variations and modifications may bemade in the features of construction and arrangement on the adaptationof the device to the various conditions of use without departing fromthe spirit and scope of my invention and improvements. I thereforereserve the right to all such variations and modifications as properlyfall within the scope of my invention and the terms of the followingclaims.

What I claim is 1. In a blind-fastener, a keeper designed to be placedbetween a blind and the wall of a house and provided with a rotatablemember for preventing birds from roosting on the keeper so mounted onsaid keeper as to be spaced from said wall and said blind, substantiallyas described.

2. In a blind-fastener a keeper provided with a slot and a rotatablemember mounted in said slot, substantially as described.

3. In a blind-fastener a keeper provided with a spur and a rotatablemember mounted thereon, substantially as described.

4. In a blind-fastener a keeper provided with a spur having a slot and arotatable member mounted in said slot, substantially as described.

5. In a blind-fastener, a keeper provided with a slot and a rotatablemember mounted in said slot and having a series of points, substantiallyas described.

6. In a blind-fastener, a keeper designed to be placed between a blindand the wall of a house and provided with a rotatable member having aseries of points, said rotatable member being so mounted on said keeperas to be spaced from said wall, substantially as described.

In testimony whereof I affiX my signature in .presence of two witnesses.

GEORGE H. FISHER.
